| |Boolean Logic|

(not True) == False == (False and True) == (False or False)

function add (const a : int ; const b : int) : int is
  block { skip } with a + b

| |Functions (long form)|

function add (const a : int ; const b : int) : int is
  block { 
    const result: int = a + b;
  } with result

| | If Statement |

type action is

| |Variant *(pattern)* matching|

const a: action = Increment(5);
case a of

| Decrement(n) -> n - 1
end

| |Records|

type person is record

end

const name: string = john.name;
